Abstract

Après qu'un solvant possédant la propriété de dissoudre ou de faire gonfler partiellement une feuille de transfert (A) pourvue d'un motif imprimé (3) sur une feuille pelable (1) est déposé sur au moins une des feuilles (A) et un matériau (12) sur lequel il faut transférer le motif, la feuille (A) et le matériau (12) sont superposés, les surfaces enduites étant disposées à l'intérieur. Le laminé résultant est comprimé et la feuille pelable est ensuite pelée, de manière que le motif est transféré sur le matériau. Etant donné que ce procédé est exécuté sensiblement sans chauffage, il est indiqué pour l'impression par transfert de matériaux présentant une faible résistance à la chaleur.
